Amazing build, thank you for the detailed writeup! Out of curiosity, if you didn't add this shielding would you expect problems with EMI? Not something I often see with DIY builds (3d printing, carbon fiber, etc).

Thank you for finding this mod and sharing! Presumably the X300 predecessor lacked this under-voltage protection circuitry since it worked at 12V. It seems odd that ASRock would bother adding this complexity when the DC-DC circuits are *more* efficient at 12V input than 19V... any ideas why...

360W: https://www.dell.com/en-us/shop/dell-360w-74mm-gan-slim-adapter/apd/492-bdnz/pc-accessories 450W: https://www.digikey.com/en/products/detail/xp-power/AQM450PS19/25905797?gQT=0

It claims to support 12V 43A (45A Max) which seems wild for something this small and cheap. I'm very curious to hear more about how it performs against listed specs. EDIT: Nevermind, I see this is 12V input

How reliable is the Pico box DCDC 200 under 200W load? Could it be pushed further with active cooling?

I found several similar premade cables: https://www.moddiy.com/categories/12VHPWR-PCIe-5.0/12VHPWR-Server-Cables/ A few options are fairly short (~30cm) so I am considering buying one (and just re-pinning if needed).

I’d totally buy this. In terms of I/O: Totally useless to me: SATA, onboard audio, VGA Probably don’t need: Ethernet Probably want: M.2 Wi-Fi It's probably too early in adoption cycle, but CAMM2 memory might allow for more room and layout flexibility. 12v-19v input flexibility would be nice...

What is the performance loss from using GPU in M.2 slot? Would there be any improvement if the Gen5 M.2 slot was used instead of Gen4?

According to this build, 7800X3D works in X600 🤯

I thought the HDPLEX 250W GaN had max 20A for 12V (240W) but this table shows 23A, which implies 276W max... I've read that the OCP is 300W, so it sounds like it might support higher draw than 20A?

I finally got my 4070S and did some preliminary testing to validate this concept. Things I found: The GPU would not power up without both sense pins grounded Grounding the sense pins to ground pins on the GPU power connector itself works (no need for connection to PSU) The GPU operates fine...

I'd love to know more about the Gen5 M.2 PCIe x4 performance with discrete GPUs. Any improvement over the Gen3 of the X300? And also compatibility with 7800X3D CPU.

Unfortunately, it seems even low/moderate-wattage models of latest GPUs use 12VHPWR power connectors. For example, 4070 Super models which require 12VHPWR connector but draw max ~220W. I plan on dedicating a HDPLEX 250W GaN PSU to power solely a 4070 Super GPU. Using all the included adapters...

Wow, that is cool you've reduced it down to just 8 wires! I did some more reading and it seems the +12V from the 24-pin connector is typically used for RAM, so trying to supply all +12V just from the 8-pin EPS connector probably won't work. Interesting PWR_OK isn't needed at all! I wonder how...

I am wondering this too. I did some investigation and I am almost certain all ventilation hole perforation at larger scale is never done with a laser. Instead, specific hole shapes are cut using a CNC-operated punch. I think one industry term is “turret punch” which refers to having several...
